San Antonio de los Alemanes church was built in the Baroque style and was designed by Pedro Sánchez. The highly decorative High Altar and three side altars belong to the 18th century and were commissioned by the last Habsburg kings of Spain.
The church was built in the 1620s-1630s by King Felipe III along with a hostel and hospital for the Portuguese migrants who moved to Madrid when Portugal was under Spanish rule. For this reason it was originally called Hospital de los Portugueses. When Portugal gained independence, Phillip IV's Queen, Mariana de Austria, dedicated the refuge to German immigrants, and changed names.
King Phillip V gave the administration of the church over to the Hermandad del Refugio (Fraternity of Sanctuary), and this group continues to manage it today, offering food and shelter to the homeless of Madrid.
The church houses frescos by Luca Giordano and Francisco Ricci. The prolific Neopolitan painter Giordano was court painter (1692-1702) to Charles II of Spain, and active for the Royal Palace and the Buen Retiro Palace.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
